spring cloud gateway modify response headers

URI variables may be used in the value and will be expanded at runtime. spring.cloud.gateway.filter.local-response-cache.timeToLive Sets the time to expire a cache entry (expressed in s for seconds, m for minutes, and h for hours). Modifying the request body is a common requirement. If it is not provided, the value of the Host request header is used. While a Gateway is running you can use kubectl scale to modify the number of replicas. It is a Spring Boot application with Spring Cloud stuff that can make it sit between clients and their requests and multiple services, where it offers features such as predicates for shaping. In configuration, you can reference the bean by name using SpEL. There is an abstract class called AbstractRoutePredicateFactory which you can extend. To configure per-route timeouts: Options. outcome: The outcome, as classified by HttpStatus.Series. .route("test1", r -> { This combined filter chain is sorted by the org.springframework.core.Ordered interface, which you can set by implementing the getOrder() method. httpStatusCode: The HTTP Status of the request returned to the client. SpringCloud Gateway After Before Between Cookie Header Host Method Path Query RemoteAddr Weight 5.1 Path spring: application: name: gateway-server cloud: gateway: routes: - id: aaa uri: http://localhost:8001 predicates: - Path=/product/** - id: bbb uri: http://localhost:8002 predicates: - Path=/order/** 5.2 Query Raw. If so, the same rules apply. Modifying the headers is simple because we can obtain a reference to the HttpHeaders map object: exchange.getRequest () .mutate () .headers (h -> h.setAcceptLanguageAsLocales ( Collections.singletonList (requestLocale))) Copy But, on the other hand, modifying the URI is not a trivial task. It does not work in a traditional Servlet Container or when built as a WAR. Writing Custom Route Predicate Factories, 17.2. The following listing shows how to add local response cache GatewayFilter: The MapRequestHeader GatewayFilter factory takes fromHeader and toHeader parameters. To see the list of all Spring Cloud Gateway related configuration properties, see the appendix. The following listing configures a SetResponseHeader GatewayFilter: This GatewayFilter replaces (rather than adding) all headers with the given name. The following example configures an RemoveJsonAttributesResponseBody GatewayFilter that uses the optional last parameter: This removes attributes "id" and "color" from the JSON content body at any level. If basedOnPreviousValue is true, the backoff is calculated by using prevBackoff * factor. The KeyResolver is a simple one that gets the user request parameter To change the default values, set the appropriate property in the spring.cloud.gateway.filter.secure-headers namespace. During your stay, take advantage of some of the amenities offered, including a 24 hour front desk, room service, and a gift shop. The following diagram provides a high-level overview of how Spring Cloud Gateway works: Clients make requests to Spring Cloud Gateway. Fork 3. The path part of the request URL is overridden with the path in the forward URL. name can contain a space-separated list of header names. Multiple matching segments are allowed. The following listing configures a ReactiveLoadBalancerClientFilter: If there is a Route object in the ServerWebExchangeUtils.GATEWAY_ROUTE_ATTR exchange attribute, the RouteToRequestUrlFilter runs. None of the prior documentation applies to what follows. To include Spring Cloud Gateway in your project, use the starter with a group ID of org.springframework.cloud and an artifact ID of spring-cloud-starter-gateway. . The parts parameter indicates the number of parts in the path to strip from the request before sending it downstream. You can configure the logging system to have a separate access log file. A per-route response-timeout with a negative value will disable the global response-timeout value. The following listing shows how it works: This style also allows for more custom predicate assertions. org.springframework.cloud.gateway.filter.factory.rewrite.ModifyResponseBodyGatewayFilterFactory body gzipchunkedHTTP Filter MonoFluxtry catch .just (xxx).doOnError () 2.2 The following example shows how to achieve the same configuration with Java: The Weight route predicate factory takes two arguments: group and weight (an int). If the fallback is called, the request is forwarded to the controller matched by the URI. URI variables may be used in the value and are expanded at runtime. Spring cloud gateway response body modification. I think i have to go for a blocking call here. Because Spring-Cloud-Gateway is a responsive architecture design based on WebFlux, traditional programming ideas are not suitable for the development of Reactor Stream in the process of migrating from Zuul. The following table describes the structure of each element (each is a route) of the response: The GatewayFilter factories applied to the route. It adds more detail to each route, letting you view the predicates and filters associated with each route along with any configuration that is available. In addition, through the spring.cloud.gateway.metrics.tags.path.enabled property (by default, false), you can activate an extra metric with the path tag: These metrics are then available to be scraped from /actuator/metrics/spring.cloud.gateway.requests and can be easily integrated with Prometheus to create a Grafana dashboard. The redis-rate-limiter.burstCapacity property is the maximum number of requests a user is allowed in a single second (without any dropped requests). How does it work? The RequestRateLimiter is not configurable with the "shortcut" notation. You can use it inside a regular Spring web handler as a method parameter. The Before route predicate factory takes one parameter, a datetime (which is a java ZonedDateTime). It also allows you to pass multi-value headers in the API response to implement things like sending multiple Set-Cookie headers. The SaveSession GatewayFilter factory forces a WebSession::save operation before forwarding the call downstream. Here is a link to someone asking about ordered filters that may provide more insight: #1341. When doing so, you need to make sure to include the default predicate and filter shown earlier, if you want to retain that functionality. The following headers (shown with their default values) are added: Strict-Transport-Security (max-age=631138519), Content-Security-Policy (default-src 'self' https:; font-src 'self' https: data:; img-src 'self' https: data:; object-src 'none'; script-src https:; style-src 'self' https: 'unsafe-inline)'. You can configure the gateway to create routes based on services registered with a DiscoveryClient compatible service registry. Spring Cloud Gateway. It requires the use of the spring-boot-starter-data-redis-reactive Spring Boot starter. Each item defines the name and the arguments of a given predicate. Post global filters are usually used in spring cloud gateway to perform operations on response like adding some headers or modifying response body or response status etc. The following example configures an after route predicate: This route matches any request made after Jan 20, 2017 17:42 Mountain Time (Denver). The following listing shows the KeyResolver interface: The KeyResolver interface lets pluggable strategies derive the key for limiting requests. Note that the $ should be replaced with $\ because of the YAML specification. The RemoveRequestHeader GatewayFilter factory takes a name parameter. Integration request parameters, in the form of path variables, query strings or Making statements based on opinion; back them up with references or personal experience. If the new named header already exists, its values are augmented with the new values. If it is not, a status of HTTP 429 - Too Many Requests (by default) is returned. These are basic guides to writing some custom components of the gateway. . The arguments are typically listed in the order that are needed for the shortcut configuration. regexp, so green and greet would match. To create a route, make a POST request to /gateway/routes/{id_route_to_create} with a JSON body that specifies the fields of the route (see Retrieving Information about a Particular Route). For more information on circuit breakers and the gateway see the Spring Cloud CircuitBreaker Factory section. To enable RouteDefinition metrics, add spring-boot-starter-actuator as a project dependency. If the response is already cached and a new request is performed with no-cache value in Cache-Control header, it returns a bodiless response with 304 (Not Modified). Red Hat 3scale provides a method for adding custom policies, but does not support custom policies. The RemoveJsonAttributesResponseBody GatewayFilter factory takes a collection of attribute names to search for, an optional last parameter from the list can be a boolean to remove the attributes just at root level (thats the default value if not present at the end of the parameter configuration, false) or recursively (true). The first step is to create a ServerHttpResponseDecorator object and override the writeWith method. The RemoteAddr route predicate factory takes a list (min size 1) of sources, which are CIDR-notation (IPv4 or IPv6) strings, such as 192.168.0.1/16 (where 192.168.0.1 is an IP address and 16 is a subnet mask). AS_IN_REQUEST: The version is stripped only if the original request path contains no version. Created 6 years ago. In order to write a Route Predicate you will need to implement RoutePredicateFactory as a bean. HttpHeadersFilters are applied to the requests before sending them downstream, such as in the NettyRoutingFilter. The default is 'B' for bytes. The To delete a route, make a DELETE request to /gateway/routes/{id_route_to_delete}. Once matched, the Gateway executes pre-request logic on each of the filters applied to the route. Spring Cloud CircuitBreaker supports multiple libraries that can be used with Spring Cloud Gateway. }, 4. exceptions: A list of thrown exceptions that should be retried. To configure Global http timeouts: 1050. .build(); The following example shows how to use the get method: The Query route predicate factory takes two parameters: a required param and an optional regexp (which is a Java regular expression). This filter takes an optional keyResolver parameter and parameters specific to the rate limiter (described later in this section). By default, the gateway defines a single predicate and filter for routes created with a DiscoveryClient. The j_spring_security_switch_user function in Cisco Unified Intelligence Center (CUIC) 8.5.4 through 9.1(1), as used in Unified Contact Center Express 10.0(1) through 11.0(1), allows remote attackers to create user accounts by visiting an unspecified web page, aka Bug IDs CSCuy75027 and CSCuy81653. The default request size is set to five MB if not provided as a filter argument in the route definition. connect-timeout must be specified in milliseconds. The following listing configures a SetRequestHeader GatewayFilter: This GatewayFilter replaces (rather than adding) all headers with the given name. XForwardedRemoteAddressResolver::maxTrustedIndex takes an index that correlates to the number of trusted infrastructure running in front of Spring Cloud Gateway. You can overwrite the names of the headers in the configuration by setting the values of the following arguments (shown with their default values): executionExceptionTypeHeaderName ("Execution-Exception-Type"), executionExceptionMessageHeaderName ("Execution-Exception-Message"), rootCauseExceptionTypeHeaderName ("Root-Cause-Exception-Type"), rootCauseExceptionMessageHeaderName ("Root-Cause-Exception-Message"). the request should only be allowed if it comes from a trusted list of IP addresses used by those You can configure additional parameters for each route by using metadata, as follows: You could acquire all metadata properties from an exchange, as follows: Http timeouts (response and connect) can be configured for all routes and overridden for each specific route. The following listing configures a websocket routing filter: After the gateway has routed a ServerWebExchange, it marks that exchange as routed by adding gatewayAlreadyRouted The XForwarded Headers Filter creates various X-Forwarded-* headers to send to the downstream service. How to modify spring cloud gateway response headers, https://github.com/spring-cloud/spring-cloud-gateway/files/3244970/code.txt, https://github.com/spring-cloud/spring-cloud-gateway/blob/master/spring-cloud-gateway-core/src/main/java/org/springframework/cloud/gateway/filter/factory/SetResponseHeaderGatewayFilterFactory.java. So a request to /hello is sent to /mypath/hello. cloudflare tunnel home assistant 19 3407 . The ForwardRoutingFilter looks for a URI in the exchange attribute ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR. Predicate: This is a Java 8 Function Predicate. You must use $\ to mean $ because of the YAML specification. Typically, there will be a name key and an args key. The response is put in the ServerWebExchangeUtils.CLIENT_RESPONSE_ATTR exchange attribute for use in a later filter. The following table below summarizes the Spring Cloud Gateway actuator endpoints (note that each endpoint has /actuator/gateway as the base-path): Displays the list of global filters applied to the routes. The following example configures a query route predicate: The preceding route matches if the request contained a green query parameter. It must be a Java System Property, not a Spring Boot property. #{@myRateLimiter} is a SpEL expression that references a bean with named myRateLimiter. This could be useful for maintenance windows. It is added to the ServerWebExchange as the ServerWebExchangeUtils.CIRCUITBREAKER_EXECUTION_EXCEPTION_ATTR attribute that can be used when handling the fallback within the gateway application. The following maxTrustedIndex values yield the following remote addresses: (invalid, IllegalArgumentException during initialization). The reason the filters are divided by the dotted line is that filters can run logic both before and after the proxy request is sent. Once a request has been marked as routed, other routing filters will not route the request again, The primary scenario is to use the fallbackUri to define an internal controller or handler within the gateway application. As a result, you can inject request headers and query parameters, for instance, and you can constrain the incoming requests with declarations in the mapping annotation. NOTE: This is not recommended for production. The following example configures /actuator/gateway/routes: This feature is enabled by default. When a request matches a route, the filtering web handler adds all instances of GlobalFilter and all route-specific instances of GatewayFilter to a filter chain. /resource). This is similar to how AddRequestHeader works, but unlike AddRequestHeader it will do it only if the header is not already there. The following example configures an AddRequestHeader GatewayFilter that uses a variable: The AddRequestHeadersIfNotPresent GatewayFilter factory takes a collection of name and value pairs separated by colon. URI variables may be used in the value and are expanded at runtime. The following listing configures a SetRequestHostHeader GatewayFilter: The SetRequestHostHeader GatewayFilter factory replaces the value of the host header with example.org. The resulting response is similar to the following: The following table describes the structure of the response: The collection of route predicates. The following example configures a PrefixPath GatewayFilter: This prefixes /mypath to the path of all matching requests. This is the number of tokens taken from the bucket for each request and defaults to 1. Retries are performed after a backoff interval of firstBackoff * (factor ^ n), where n is the iteration. When communicating over HTTPS, the client initiates a TLS handshake. Value 3.9. Spring Cloud Gateway can forward OAuth2 access tokens downstream to the services To write a custom global filter, you must implement GlobalFilter interface as a bean. The url parameter should be a valid URL. Setting this value to zero blocks all requests. AddResponseHeader is aware of URI variables used to match a path or host. spring.cloud.gateway.filter.local-response-cache.size: Sets the maximum size of the cache to evict entries for this route (in KB, MB and GB). You can read more about them in the. Displays the list of routes defined in the gateway. status codes that if returned will cause the circuit breaker to be tripped. Well occasionally send you account related emails. This can be used with reverse proxies such as load balancers or web application firewalls where In addition, you can configure this filter once by using spring.cloud.gateway.default-filters and have it applied to all routes. to the exchange attributes. The following example configures a Spring Cloud CircuitBreaker GatewayFilter: To configure the circuit breaker, see the configuration for the underlying circuit breaker implementation you are using. The lowercase full name of the secure header needs to be used to disable it.. Create a ClientResponse object that will hold both the body and the headers: Then extract the body and encrypt it using the EncryptDecryptHelper class. Additionally, to set a multi-valued header, use the header name multiple times like AddRequestHeadersIfNotPresent=X-Request-Color-1:blue,X-Request-Color-1:green. Note that this example also demonstrates the (optional) Spring Cloud LoadBalancer load-balancing (defined by the lb prefix on the destination URI). This is the rate at which the token bucket is filled. The filter also looks in the ServerWebExchangeUtils.GATEWAY_SCHEME_PREFIX_ATTR attribute to see if it equals lb. You can use the ModifyRequestBody filter to modify the request body before it is sent downstream by the gateway. To disable it, set the following property: This will default to true in a future release. The following listing shows the definition of the RouteDefinitionLocator interface: By default, a PropertiesRouteDefinitionLocator loads properties by using Spring Boots @ConfigurationProperties mechanism. To write a GatewayFilter, you must implement GatewayFilterFactory as a bean. Configuring Route Predicate Factories and Gateway Filter Factories, 5.10. Spring Cloud Gateway aims to provide a simple, yet effective way to route to APIs and provide cross cutting concerns to them such as: security, monitoring/metrics, and resiliency. Spring Cloud Gateway Encryption/Decryption of Request/Response | by Sumant Rana | Level Up Coding Write Sign up Sign In 500 Apologies, but something went wrong on our end. It provides a convenient method to apply a transformation to JSON body content by deleting attributes from it. The Host route predicate factory takes one parameter: a list of host name patterns. In the example below the call consumingServiceEndpoint/users/1 will be redirected to inCaseOfFailureUseThis/users/1. Sumant Rana 77 Followers Embark on a cloud native journey Follow More from Medium The default list of headers that is removed comes from the IETF. The default is http|https|ftp|ftps. To add this functionality to the gateway, you need to add the TokenRelayGatewayFilterFactory like this: and it will (in addition to logging the user in and grabbing a token) per-route http timeouts configuration via configuration, per-route timeouts configuration using Java DSL, Example 73. reverse proxies. This approach is vulnerable to spoofing, as a malicious client could set an initial value for the X-Forwarded-For, which would be accepted by the resolver. This filter also implements the automatic calculation of the max-age value in the HTTP Cache-Control header. Filter: These are instances of GatewayFilter that have been constructed with a specific factory. .filters(f -> f.addRequestHeader("header1", "header-value-1")) To be remotely accessible, the endpoint has to be enabled and exposed over HTTP or JMX in the application properties. 4.1. For example, given a Gateway that has 1 replica, the following will . which are java ZonedDateTime objects. connect-timeout must be specified in milliseconds. The following example configures such a fallback: The following listing does the same thing in Java: This example forwards to the /inCaseofFailureUseThis URI when the circuit breaker fallback is called. return routeBuilder.routes() This vulnerability is known as HTTP Response Splitting. API gateway provides a unified access for services in microservices architecture. APIcast standard policies The following listing defines a set of default filters: The GlobalFilter interface has the same signature as GatewayFilter. The following listing configures a RemoveResponseHeader GatewayFilter: This will remove the X-Response-Foo header from the response before it is returned to the gateway client. The Cookie route predicate factory takes two parameters, the cookie name and a regexp (which is a Java regular expression). If the input header does not exist, the filter has no impact. The header is added to the response if configured with the following property: The StripPrefix GatewayFilter factory takes one parameter, parts. The following defaults are configured for Retry filter, if enabled: exceptions: IOException and TimeoutException. and puts it in a request header for the downstream requests. For example, you might want to extract the trailing elements of a path to pass them downstream: All the features of Spring MVC and Webflux are available to gateway handler methods. The maxSize is a DataSize type, so values can be defined as a number followed by an optional DataUnit suffix such as 'KB' or 'MB'. This filter also automatically calculates the. The following example configures a weight route predicate: This route would forward ~80% of traffic to weighthigh.org and ~20% of traffic to weighlow.org. By default, if the KeyResolver does not find a key, requests are denied. Looking for a place to stay in Gunzenhausen? The After route predicate factory takes one parameter, a datetime (which is a java ZonedDateTime). SetResponseHeader is aware of URI variables used to match a path or host. A gauge metric named spring.cloud.gateway.routes.count will be added, whose value is the number of RouteDefinitions. This filter works only with HTTP (including HTTPS) requests. In order to share Routes across a cluster of Spring Cloud Gateway instances, RedisRouteDefinitionRepository can be used. The stripVersionMode parameter has the following possible values: NEVER_STRIP, AS_IN_REQUEST (default), and ALWAYS_STRIP. To provide the same CORS configuration to requests that are not handled by some gateway route predicate, set the spring.cloud.gateway.globalcors.add-to-simple-url-handler-mapping property to true. Sign in The gateway maintains a client pool that it uses to route to backends. It adds the Host header, scheme and port of the current request to any existing Forwarded header. 3,AddResponseHeader GatewayFilter Factory. AddRequestParameter is aware of the URI variables used to match a path or host. Zuul profile. The following example configures a DedupeResponseHeader GatewayFilter: This removes duplicate values of Access-Control-Allow-Credentials and Access-Control-Allow-Origin response headers in cases when both the gateway CORS logic and the downstream logic add them. It may be the integer value 404 or the string representation of the enumeration: NOT_FOUND. Since the request can be read only once, we need to cache the request body. By using the fluent Java API, you can use the and(), or(), and negate() operators on the Predicate class. It seems the response header cannot be modifed in post filter,the following is my code,please tell me a way to solve this problem. Those values are then available for use by GatewayFilter factories. @ryanjbaxter thanks, the core code is a filter https://github.com/spring-cloud/spring-cloud-gateway/files/3244970/code.txt ,but it can't modify header in a post filter,is it a right way writing like this? GitHub Gist: instantly share code, notes, and snippets. This filter sets a request attribute that the routing filter inspects to determine if the original host header should be sent rather than the host header determined by the HTTP client. Here, you can modify requests and responses before or after sending the downstream request. The following example below is invalid: The Redis implementation is based on work done at Stripe. NEVER_STRIP: The version is not stripped, even if the original request path contains no version. If you would like us to look at this issue, please provide the requested information and we will re-open the issue. You can also define a rate limiter as a bean that implements the RateLimiter interface. The redis-rate-limiter.replenishRate property defines how many requests per second to allow (without any dropped requests). The previous sample defines the Cookie Route Predicate Factory with two arguments, the cookie name, mycookie and the value to match mycookievalue. You can combine multiple route predicate factories with logical and statements. By default, the RemoteAddr route predicate factory uses the remote address from the incoming request. URI variables may be used in the value and are expanded at runtime. This filter (which configures the local response cache per route) is available only if the local response global cache is enabled. Want to remove the "warning cannot modify header information" error from your WordPress website? The following example shows how to do so: You can route gateway routes to both HTTP and HTTPS backends. To enable this kind of repository, the following property has to set to true: spring.cloud.gateway.redis-route-definition-repository.enabled You signed in with another tab or window. See the documentation for @RequestMapping in Spring MVC for more details of those features. URIs defined in routes without a port get default port values of 80 and 443 for the HTTP and HTTPS URIs, respectively. ServerWebExchangeUtils.isAlreadyRouted takes a ServerWebExchange object and checks if it has been routed. This is the full configuration of the shortcut configuration of the Cookie predicate shown above.
